Answer:
Step-by-step explanation:
Answer:
c) 11
Step-by-step explanation:
g(x)= x² + 2
x = 3
substitute x for 3
g(3) = (3)² + 2
g(3) = 9 + 2
g(3) = 11
Answer:
x = 59
Step-by-step explanation:
= 5 ( raise both sides to the power of 3 )
(
)³ = 5³
2x + 7 = 125 ( subtract 7 from both sides )
2x = 118 ( divide both sides by 2 )
x = 59
